IMPORTANT: O-ring and seat surfaces for O-ring
must be clean, dry, and oil free so
O-ring does not slip.
7. Thoroughly clean O-ring and seat surfaces in housing
and seal ring using volatile, non-petroleum base
solvent and lint-free tissues.
NOTE: A volatile, non-petroleum base solvent or talcum
powder can be used as a lubricant. Solvent must
not damage the O-ring or leave an oil residue.
8. Apply equal pressure with fingers at four equally
spaced points on seal face surface. Seal ring and
O-ring must "pop" down into place so O-ring is tight
against seal bore and seal is installed squarely.

using clean oil and lint-free tissues.
